Figure F11. Magnetic susceptibility (MS) measured along half cores from Hole U1309B in diabase Unit 20 (Core 305-U1309D-19R). Edited data (blue) are measurements made >5 cm from the edge of a core piece, so values are most reliable; however, overall pattern is essentially the same as for all data (gray). Note the lower MS in the middle of this diabase unit (MS remains high in Core 305-U1309D-20R below 99 mbsf).
